`IMPROVEMENT iN SIPHoNs.

Specication'forming part of Letters Patent No. 56,597, dated July 24, 1866.

To all whom fit may concern Be it known that I, JOSEPH M. NAGLEE, of Philadelphia, Pennsylvania, have invented certain Improvements in Siphons; and I do hereby declare the following to be afull,clear, and exact description of the same, reference being had to the accompanying drawing, and to the letters of reference marked thereon.

My invention consists, rst, in the combination, with a siphon, substantially as described hereinafter, of an elastic air-vessel and certain valves, so that the air may be withdrawn from the siphon by the alternate compression and expansion of the said air-vessel; secondly, of an adjustable rod, combined with the short arm of the siphon, in order that the lower end of the latter lnay be maintained above the sediment in the bottom, of the vessel from which the liquid has to be withdrawn.

In order to enable others to make and use my invention, I will now proceed to describe its construction and operation.

The figure in the accompanying drawing, which forms a part of this specication, represents my improved Siphon in section.

A is a Siphon-tube of the usual form, a being the short arm, and a the long arm, and near the lower end of the latter is an ordinary stop-cock, B. Near the upper end of the arm a is a small valve-chest, b, which contains a valve, c, opening outward, and which communicates, through an opening, a2, with theinterior of the siphon-tube.

A hollow plug, d, is screwed into the chest, and is attached to one end of an elastic airvessel, C, to the other end of which is secured a valve-chest, b', containing a valve opening outward, and coniined to the chest by a screwplug, el.

In the upper end of the arm a is an opening, q, which is closed by a valve, t, on one end of a spring-lever, D.

To the arm a of the siphon-tube, near its lower end, is secured a notched plate, f, and round the latter, as well as round the tube, ex tends an adjustable band, E, to which is secured one end of arod, g, the latter being guided by a projection, h, at the lower end of the arm, and at the upper end of the rod is a springcatch, t', the end of which bears against the notched plate f.

In using the siphon above described the short arm a is introduced into the liquid, and the cock B is so turned as to close the long arm a', when the operator, grasping the vessel C in his hand, alternately compresses the same and allows it to expand, the air being expelled through the opening as the vessel is compressed, and the latter being refilled with air from the siphon as it resumes its sha-pe, this operation being4 continued until all, or nearly all, the air in the siphon is withdrawn. The cock B is then turned, when the liquor will be discharged in the usual manner.

When itis not desired to disturb the sediment at the bottom of the vessel from which the contents have to be withdrawn, the rod g is adjusted so as to extend a sufficient distance beyond the end of the arm a to maintain the latter above the sediment, the end ofthe spring t' engaging in the notches of the plate j', and preventing the rod g from sliding upward.

As the operator removes the siphon he places his thumb on the lever D, and by raising the valve t admits the air into the tube, the rapid discharge oi' the liquid in the arm a being thus e'ected.

In ordinary siphons it is customary for the operator to apply his mouth to the end of the long arm, and thereby exhaust the air from the tube, or else to displace the air by filling the tube with water, both methods being troublesome and inefficient, especially where acids or other corrosive liquors are operated on.

By the use of the instrument above described the air may be quickly exhausted from the siphon without inconvenience to the operator and without wasting the liquid.

The devices are simple and may be readily attached to siphons of the ordinary construction.

It will also be seen that by the use of the adjustable rod g the clear liquid can be withdrawn from a vessel without danger of disturbing the sediment, and that the usual tardy discharge of the liquid from the arm a is prevented by the use ot' the lever D and its valve t.

I am aware that an elastic vessel has heretofore been combined with a siphon, so that the latter can be filled with fluid by compressing the vessel and then allowing it to expand. Such a device, however, is objectionable, in

asmuch as it is necessary to employ an airvessel of nearly as great a capacity as thatof the siphon, the vessel, when used with siphons of a large size, being bulky and difcult to operate.

In the device above described a small elastic vessel capable of being readily grasped by the hand can be efficiently used With siphons of any size, as, owing to the valves, the vessel can be filled and discharged as often as necessary to remove all the air from the siphon.

l claim as my invention and desire to secure by Letters Patent- 1. The elastic air-vessel C and valves c c', combined with a Siphon, substantially as and for the purpose described.

2. The combination of the adjustable rod g With the short arm of a siphon, substantially as set forth, for the purpose specified.
